I am so freaking out here. I was suppost to start my period two days ago,today marks three if I don't start. We have been using condoms every time we have sex. I'm freaking out because I already have an almost 2 year old and an almost 3 month old and idk if I can handle 3 babies right now plus my mom would kill me if I told her I was pregnant again after just having another baby girl.. I don't think any of the condoms broke but they could have had a hole at the tip right. I'm hoping I'm not because we are financially not ready for three two is just fine for right now.
